Epidemics of COVID-19 are occuring at different times across the United States so it is important to compare the spread of an epidemic in a given state with the appropriate stage in other countries. The following figures show the cumulative number of cases in a state by number of days since the 100th case, number of days since the 1st case, and by calendar date, respectively.
